TENCEL™ Baby Sleep Sack 1.0 TOG - English Garden

Roses, peonies, and the kind of floral that looks better in person than on the screen. 1.0 TOG. The year-round sleep bag. Built for nurseries between 69 and 75°F, the most common US bedroom temperature overnight. If you're only buying one sleep bag, this is the one. Material. TENCEL™ Lyocell, with DuPont™ Sorona insulation for warmth without bulk. TENCEL™ is a wood-pulp fiber spun in a closed-loop process — 99% of the water and solvents get recycled back into the production line. Lenzing produces it; we buy from Lenzing directly. It's softer than cotton, smoother than bamboo rayon, and holds up to fifty wash cycles with less pilling and less thinning. The Sorona is a plant-based polymer fiber from corn-derived feedstock — it traps warmth at a fraction of the loft of polyester, which is how this bag stays a 1.0 TOG without feeling like a winter parka. The print. Vintage botanical lithograph translated to fabric — soft mauves and sage on ivory. Construction. Sleeveless. 2-way zipper that opens from the bottom so the baby stays inside the bag during diaper changes — open the bottom, change, zip up, no temperature shock. Hidden seams against the skin and a fabric guard at the zipper top for babies with eczema or sensitive skin. The neckline is engineered to fit snug at the shoulders without restricting breathing — that's the safe-sleep geometry. TENCEL™ vs bamboo rayon. Bamboo rayon feels softer on the first wash. TENCEL™ feels the same on the fiftieth. The difference shows up between months four and six of weekly washing — bamboo rayon starts to pill at the seams and thin at the back where the baby sleeps. TENCEL™ keeps its surface. For a sleep bag your baby is in for nine months of the year, that gap matters more than the first-touch test. Independent recognition. Part of Loulou Lollipop's Good Housekeeping 2025 Parenting Award-winning sleep sack line. Adjacent TOGs in the same print. Room running warm?

Common questions Is TENCEL™ better than bamboo for baby sleep sacks? TENCEL™ Lyocell is a wood-pulp fiber spun in a closed-loop process. It pulls moisture off the skin faster than bamboo rayon and pills less through wash cycles. Bamboo rayon is softer at first feel; TENCEL™ holds its hand after fifty washes. For sleep sacks that get washed weekly, TENCEL™ lasts longer. What TOG rating should my baby wear? Match the TOG to the room. 0.5 TOG for 75–81°F. 1.0 TOG for 69–75°F, the most common nursery temperature in the US. 2.5 TOG for 61–68°F cold nurseries. A nursery thermometer costs $10 and removes the guesswork. What should baby wear under a 1.0 TOG sleep sack? A short-sleeve bodysuit at the top end of the range (74–75°F), a long-sleeve bodysuit in the middle (70–73°F), or a footed sleeper at the cool end (69–70°F). The TOG number is the bag's contribution — the under-layer fine-tunes. Browse all baby sleep sacks .
